Re: Asking for maintainer for astronomical packages and some important (and related) issues



Sorry for the late answer.. you will see in a minute why I took some more 
time to answer on this.

No, they _are_ redistributable, they just can't be modified. I would 
suggest you read the copyright info in the yale/gliese packages as well as 
the copyright info in the data/ dir of the spacechart package (which 
provides the Hipparcos data set)

Not really, if you see how the (new) starplot package manages it is quite
easy.  If it finds star data under /usr/share/stardata it converts it to 
its format and places it in /usr/share/starplot. That way you can remove 
dependancies. Also, the gliese/yale packages call the conversion routine (a 
simple program) if they are installed _after_ the starplot package.

The current status (with the new uploads I've made) is that gliese/yale are 
indepent packages that provide the star catalogue in the format provided 
upstream (which is a standard format in which all catalogues are provided 
BTW).

Ok. Great. Please read the (updated) debian/copyright of yale/gliese, there 
are alternatives to ADC which provide the same catalogues.

As a matter of fact I believe all of these star catalogues are in the 
public domain (like the Hipparcos dataset is), but it does not hurt to be 
cautious. It would be a good idea to contact an astronomer which might help 
clarify this.

Well. I already fixed it (for both), and I have sent new upstream.

Great.

Agreed.

Great. I have made new uploads of starplot/spacechart in order to fix many 
of the lintian bugs and provide the latest versions. I've also made uploads 
of gliese/yale further clarifying where to obtain the upstream version and 
the copyright issues, as well as notes on how should they be used by other 
packages (I believe the way starplot handles them is the best). 

Please do take a look at them and send me any comment you might find  
useful. Maybe you can prepare uploads for the currently unmaintained 
packages (gstar) and contact the upstream maintainers of starplot, 
spacechart, openuniverse, etc..

I would rather distribute each catalogue in its own and have them Provide a 
virtual package 'star-catalogue'.

I've had one of co-maintainership. I believe that these packages should be 
better be co-maintained since it's too much work to have them all be 
handled by a single person.
